Item Open Access A Fibre Optic Long Period Grating Immunosensor for Campylobacter jejuni with Enhanced Sensitivity by Bacterial Staining(Cranfield University, 2018-10-22 10:29) Rendon Romero, AntonioPoster presented at the Cranfield Doctoral Network Annual Event 2018. Campylobacteriosis is one of the most widely reported bacterial cause of gastroenteritis in humans in the world. One of the bacterial species that most causes the disease is Campylobacter jejuni. The detection of Campylobacter jejuni by sensitising the surface of an optical fibre long period grating (LPG) with covalently attached rabbit polyclonal antibody is explored. The sensitivity of the sensor is enhanced by bacterial staining allowing the detection of concentration as low as 102CFU/mL. Finally, the selectivity of the sensor against other bacterial species is evaluated.Item Open Access A numerical study of deep borehole heat exchangers in unconventional geothermal systems(Cranfield University, 2018-10-22 10:16) Renaud, ThéoPoster presented at the Cranfield Doctoral Network Annual Event 2018.The geothermal energy sector is facing numerous challenges related to heat recovery efficiency and economic feasibility. Ongoing research on superheated/supercritical geothermal system, potentially representing a intensive amount of energy, is developed in Europe notably the Iceland Deep Drilling project (IDDP). The well IDDP-1, which reached a magma intrusion at a depth of 2100 m, raised new opportunities to untap the geothermal potential near shallow magmatic intrusions. Given their highly corrosive nature, geothermal fluids weaken the wellbore’s integrity during conventional geothermal production. Deep Borehole Heat Exchangers (DBHE) that do not require fluid exchange between the surface and the wells represent a strategic alternative to recovering heat from these unconventional geothermal resources, while minimising the risk of in-situ reservoir damage. The thermal influence and heat recovery associated with a hypothetical DBHE drilled into the IDDP geological settings were investigated via Computational Fluid Dynamics (CFD) techniques until 10 years of production, when the system reaches full equilibrium. Two wellbore designs were simulated, based on simplified geological properties from the IDDP-1 well description. The results show that, during the first year of production, the output temperature is function of the working fluid velocity before reaching pseudo-steady state behaviour. The cooling perturbation near the bottom hole is shown to grow radially from 10 to 40 m between 1 and 10 years of production, and the output thermal power calculated after 10 years reaches 1.2 MW for a single well.Item Open Access Astronaut Playscapes - Table Football in space - a crazy idea … or a sensible contribution to keeping astronauts functioning in complex space systems?(Cranfield University, 2021-11-23 18:26) Cullen, David; Goument, LauraPoster summarising the status of the Astronaut Playscapes concept as of November 2021Item Open Access Characterisation of large diameter through-thickness metallic pins in composites(Cranfield University, 2022-09-29 14:53) Neale, Geoffrey; Saaran, Vinodhen; Dahale, Monali; Skordos, AlexPoster and extended abstract presented at the International Conference on Manufacturing of Advanced Composites (ICMAC 2022)Item Open Access Characterisation of Wire Arc Additive Manufactured Superalloys(Cranfield University, 2024-02-16 15:47) James, WilliamCharacterisation of two superalloys to understand the response of Wire Arc Additive Manufactured (WAAM) superalloys for high temperature applications.

There is no consensus in the literature on a concise and precise definition of SCM nor its underpinning theory(s). A rigorous theoretical framework has not yet been developed; the existing models like Supply Chain Operations Reference (SCOR) and the Global Supply Chain Forum (GSCF) models lack the details called for in a holistic model that encompasses the essence of SCM and integrates the best features of the existing models and covers their shortcomings.The argument in the literature is that: “research and practice would be improved if a single definition were adopted” (Mentzer et al., 2001); “closing the gap between SCM theory and actual practice would be the development of a single, unifying SCM framework that both incorporates the best aspects of the existing, widely used frameworks and addresses their current limitations” (Moberg et al., 2008). However, in this research, the author argues that a consensus on a unified conceptual/theoretical framework of SCM will contribute to solving those theoretical issues.The literature has shown that most of the research approaches which were used to solve those theoretical issues were process-oriented or business functions-oriented, that is, the focus was on what firms and organisations are doing, where they do it, or how they do it. However, the main gap the researcher has identified through the study and the analysis of the literature is that an Objective-Oriented approach has not been investigated in resolving those theoretical issues. Also, the researcher found that the objectives of SCM and supply management as a whole were scattered in the literature. In this study, the researcher objective is to investigate the viability of using this approach in solving those theoretical issues.The researcher found that an appropriate research methodology to investigate the viability of an Objective-Oriented approach would be to apply the Grounded Theory research methodology, which is a well known qualitative research methodology that is used in developing theories or theoretical frameworks from data (grounded) through line-by-line coding and categorising process. Recent work reported by Randall and Mello, (2012) recommended the use of the Grounded Theory research methodology as they established that grounded theory “can be an appropriate tool for creating theory in supply chain research”. This methodology has also been recommended by Denk, Kaufmann and Carter, (2012) and Manuj and Pohlen, (2012)Therefore, this research focuses on the implementation of the Grounded Theory research methodology through an Objective-Oriented coding system that will analyse multiple data resources including the literature, websites, recorded lectures and recorded interviews. Through this approach, the researcher was able to: conceptualise SCM, identify the theory behind it, define the concept precisely and concisely and develop a unified model that visualises SCM.Item Open Access Control for Motion Sickness Minimisation in Autonomous Vehicles(Cranfield University, 2018-10-22 10:13) Htike, ZawPoster presented at the Cranfield Doctoral Network Annual Event 2018. Autonomous vehicles or self-driving vehicles are expected to become a wide scale deployment for public use in the very near future. Recent study shown that there will be increase in frequency and severity of motion sickness due to engaging in non-driving tasks. This establishes motion sickness as being the elephant in the room and the increase in occurrence of motion sickness is predicting to be a limitation to the successful introduction of full vehicle automation. Motion sickness is a condition marked by symptoms of nausea dizziness, and other physical discomfort. The accepted cause of motion sickness is being the sensory conflict between inputs from the visual, vestibular and somatosensory systems of human body. Factors that might increase or decrease the severity of sickness symptoms includes ages, genders, alcohols, drugs, motion environments, other environmental and psychological aspect. Nevertheless, motion sickness in road vehicles is most closely related to low-frequency fore-and-aft, lateral, yaw acceleration. The range of these frequencies stated in the Standards guideline (International Standard, British Standards and Military Standards) for human exposed to whole-body mechanical vibration and shock, are in the range between 0.1 to 0.5 Hz. Previous experiments studies also shown that passenger motion sickness increases with increased exposure to lateral motion at low frequencies less than 0.5 Hz. This project aims to develop a control strategy that could minimise motion sickness in autonomous vehicles. The first part of the project explores the empirical formulations outlined in the Standards to evaluate motion sickness as a form of predicted illness rating or motion sickness incidence. A simple optimisation algorithm is developed to investigate the effectiveness of reducing motion sickness based from such formulations. The second part of the project looks at the sensory conflict theory for estimating motion sickness by adopting the existing 6-DOF subjective vertical conflict model. This model would later incorporate with vehicle model, and an optimal control strategy would be implemented to minimise motion sickness.Item Open Access Design and Integration of a Hybrid Electric Fan Propulsion System(Cranfield University, 2018-10-18 10:00) Mastropierro, FrancescoPoster presented at the Cranfield Doctoral Network Annual Event, September 2018.Design and Integration of an Electric Fan Propulsion System for Hybrid Aircraft Electrification is one of the most promising trend for sustaining future aviation beyond the limits of current propulsion technologies. Advantages include lower emissions, higher efficiency components, better energy management and synergies with alternative technologies. Current limits are in higher costs, inferior power density and shorter ranges. Hybrid electric propulsion looks for synergies between current state-of-the-art engines and novel electric motors/batteries, the latter considered as black boxes.The research project aims to investigate quantitatively the unexplored design space for an electric fan propulsion system fitted on a specifically-designed nacelle for regional aircraft. The study entails with the assessments of the overall arrangement and geometry design, evaluating effects of internal pressure losses and cooling air requirements. A viable solution for the organization of the internal volume is the installation of a variable area nozzle. Its adoption would optimise fan performance along a defined mission, allowing a consistent reduction in power and size of electrical components, estimated up to 15%.Additional objectives are the assessment of critical integration aspects of the hybrid technology, such as trade-offs between size and weight of units, degree of hybridization, strategies for efficient energy usage. A techno-economic assessment would top the project, defining viability and economic feasibility of the technology. A realistic evaluation of the uncertainties associated will be included as it is essential to provide solid background to any result.The research uses a combination of dedicated performance software and mainly relies on CFD calculations for the investigation of the internal flows.The project is relevant in the context of evolving aerospace industry, as major companies are consistently investing in electric aviation. It provides contribution to existing knowledge and foundation for future research in the field, both at academic and industrial level.Item Open Access Developments in CO2 Compression and Purification Unit (CPU) for Oxy-fuel Combustion Power Plant(Cranfield University, 2018-10-22 10:25) Yan Yan, HarryPoster presented at the Cranfield Doctoral Network Annual Event 2018.Developments in Carbon Dioxide Compression and Purication Unit (CPU) for Oxyfuel Combustion Power Plant. Oxyfuel combustion technology as one of three major carbon capture technologies, which has been largely investigated from bench scale to demonstration scale. The difference of carbon dioxide gas quality in oxyfuel combustion technology which require additional process with high cost and energy penalty than that of pre- and post-combustion capture technology. In this work, previous work from the oxyfuel combustion demonstration projects and industrial technologies of CPU led by Air Products, Air Liquide, Linde and Praxair have been reviewed. A novel concept that using wet ozone direct oxidation absorption for simultaneous removal SOx and NOx for CPU has been proposed and validated in Aspen Plus. The results indicated that 99% NO, 90% NO2 and nearly 100% of SO2 was removed at pH 11 before compression and the purity of product CO2 can achieve 99.7%. Comparison with the previous technologies, this method achieve high purity of product CO2 with simplified process and can realize the negative emission in oxyfuel combustion power plant.Item Open Access Graphic abstract(Cranfield University, 2022-06-07 12:41) Deja, Jakub; Dayyani, Iman; Skote, MartinModelling and Performance Evaluation of Sustainable ArrestingGear Energy Recovery System for Commercial AircraftItem Open Access IEEE sensors 2016 poster(Cranfield University, 2016-10-21 15:18) Barrington, James; James, Stephen; Tatam, Ralph; Partridge, MatthewConference poster for IEEE sensors 2016 conference.

AD is commonly used to treat highly concentrated wastes, such as waste sludge from municipal wastewater treatment plants. Similar, trade wastes (TWs), wastewaters generated from industrial or production processes, known to contain high levels of organics as compared to domestic wastewater, are often treated in anaerobic systems. The treatment of sludge in AD has been seen to be enhanced with the addition of TWs. However, as any biological system, the bacteria may be affected by toxic compounds present in the substrate, and TWs are a potential source of compounds affecting anaerobic bacteria with, for instance, ammonia, heavy metals, and fats oils and greases. Therefore, there is a need to understand the possible impact of those compounds in AD of TWs and sludge. This research aims to understand the limitations and benefits of using TWs in anaerobic digesters treating wastewater sludge and in particular the impact TWs may have on biogas production and stability of the reactors. The impacts of using TWs on the AD of sludge were assessed in this project by testing controlled addition of the compounds of interest in batch reactors treating sludge. This data will be compared to the characteristics of TWs to select them for further experiments. The final result will be a decision support tool that could be used for water companies to decide the TWs to be added to the digester.Item Open Access P15_ Gun Demonstration of Nitrogen-Doped Boron Propellant.pdf(Cranfield University, 2023-07-05 16:31) Gill, PhilipGUN DEMONSTRATION OF NITROGEN-DOPED BORON PROPELLANTS Dr THELMA G.
